Easy and fast functionalization of polypropylene and its efficiency in arsenic (V) removal Fácil y rápida funcionalización del polipropileno y su eficiencia en la remoción de arsénico (V)

Abstract

Abstract This article presents an easy functionalization of polypropylene with the ability to remove arsenic (V) upon contact with the aqueous solution, retaining it on its surface, being easy to remove, and complying with the WHO limit. Functionalized polypropylene requires 10 minutes of reaction in UV radiation. The maximum removal was 68% of As (V) at an initial concentration of 1 mg/L and 12 hours of contact time. We found that the removal percentage increased with increasing the number of functionalized membranes three in the arsenic solution reaching the removal of 80% of the initial concentration of 48 μg/L, achieving the maximum concentration of As (V) in water established by the WHO. Keywords: Arsenic (V); grafting polymerization; functionalized polypropylene; Uv irradiation, carboxylic group.
